Support FIDO2 1/2FA.

It provides significantly quicker authentication processes, and significantly less chance of phishing, since the user cannot be convinced to enter a credential (although TOTP mostly solves that, too).

Examples

Discourse, Forgejo, KeyCloak, Mastodon and Addy support it. GitLab and Matruix's Synapse are tracking their implementation of it.

Repostage

Implementation is tracked at github.com/codidact/qpixel/issues/1836.

Multiple keys

Mgmt: If you do this, please please please support multiple keys.

Michael‭, does your rationale equivalate what phabricator.wikimedia.org/T230042#11185862 describes?

Close, but with FIDO2, not TOTP. With TOTP, you are making a six-digit rotating password "1/N as safe" for each device. It can drop into brute-force territory with a handful of devices. That's not equivalent to FIDO2, which has substantially longer challenge/response keys.

AWS for a while only permitted one FIDO2 device, so unless you had YubiKeys that were special-ordered to have the same IV... if you lost it, you were completely locked out. FIDO2 almost needs to have the ability to register multiple devices with an identifier.

Michael‭, I have all FIDO2 and U2F devices (registered via WebAuthn) registered in my credential manager (Bitwarden), via its WebExtension. I don't disagree that what you propose is sensible, but certainly appears to be an inherent disadvantage of physical key storage.
